Canon Pixma MG5650: Printer fails to pull in paper and makes loud noises while trying. Error code: 1003 No paper. However, I tried paper in different thicknesses, in different amounts, tried to push, to adjust, whatever. Assuming some mechanical part is broken, how can I detect this myself and how could I possibly repair it? Canon’s support in this, of course, is useless. Thanks! Ah btw, this problem just occurred all of a sudden, after having printed 15 out of 30 pages (duplex).
Sounds like the pinch rollers are dirty with paper dust so they can’t grab the paper. Using cotton swabs (Q-Tip’s) and isopropyl alcohol to wash them down. See if that fixes things you may need to replace them if they are dried out. You also will need to use some can’ed air to blow away the junk around the sensors as well.
Pixma no paper alert with paper in the printer, not picking up paper. Cleaned the rollers, paper tray etc. No joy. Then noticed a small white plastic curved plate - 15mm*5mm - with a spring at the rear of it, which was definitely to be in the paper path. Pushed this back into the slot behind it, pushed hard, and it clicked back into place. Do not know how this became dislodged, nor function, but that was the problem.
